DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in FIGS. 1-5 of the drawing, a liquid serving device, generally designated 10, is shown to comprise a decanter including a flask 11 having a bowl l2 and generally tubular neck portion 13 upstanding from the bowl portion 12. The invention comprehends the-provision of a unitary spout and handle element, generally designated 14, mounted on the flask neck 13. More specifically, the spout and handle element 14 includes an upper spout portion 15, a tubular body portion generally designated 16, and a handle portion 17. The element l4 herein comprises a one-piece structure wherein the portions 15, 16 and 17 are integrally .formed as by molding ofthe element from a suitable plastic such as polyethylene.

As best seen in FIG. 3, the flask neck 13 includes an upper end 18 and an annular radially enlarged portion 19 spaced below upper end 18 and defining a downwardly facing shoulder 20. The shoulder 20 effectively comprises the upper portion of a reentrant surface annular recess 21.

The tubular body portion 16 of the element 14 includes an upper continuously annular portion 22 and a lowerdiscontinuously annular portion 23 disposed subjacent the upper portion 22 to extend about the neck 13 subjacent the lower portion 19 of the neck 13.

As shown in FIG. 3, the spout projects upwardly from the upper portion 22 and includes an inturned flange 24 engaging the upper end 18 of the neck to define a seal therewith. To augment the seal of the flange 24 with the neck 13, the upper body portion 22 is provided with a radially inwardly and axially downwardly opening recess 25 spaced below the flange 24 and adapted to receive thereinan annular O-ring 26 which is sealingly compressed between the upper body portion 22 and the neck 13.

The lower portion 23 of the body portion 16 is made discontinuously annular by providing a pair of slots 27, each of which includes a longitudinally extending portion 28 and a transverse portion 29. As best seen in FIGS. 2 and 4, the slot portions 29 may extend less than 180 from the slot portions 28 and the free ends 30 of the lower body portion 23 defined by the slots comprise tab portions 30 received in oppositely opening recesses 31 in a base 32 of the handle 17 integrally formed with the tubular body portion 16 to extend radially outwardly therefrom. The slot portions 28 extend from the bottom 33 of the handle base portion 32 less than fully upwardly therethrough and in the illustrated embodiment, as shown in FIG. 3, extend upwardly approximately one-half the height thereof. The recesses 31 effectively define a thin web 34. The body portion free ends 30 are juxtaposed to the opposite sides 35.

The lower body portion 23 further defines a radially inwardly projecting annular bead 36 adapted to be received in the recess 21 of the flask neck 13 and defining an upwardly facing upper shoulder portion 37 which engages the downwardly facing shoulder defined by the upper portion of recess 21. Means for securing the element 14 to the flask neck 13 are provided in the form of bolt 38 including a shank 39 extending through the respective tabs 30 and web 34, and a nut 40 threadedly secured to the end of the shank 39, as shown in FIGS. 2 and 4.

Thus, by tightening the securing means 38,40, the tabs 30 are drawn together toward web 34 thereby constricting the lower body portion 23 about the flask neck 13 and effectively positively bringing the bead 36 into interlocked relationship with the neck 13 in the recess 21 thereof. As the lower body portion 23 is expandable as a result of the provision of the slots 27, as well as the flexibility thereof, the body portion 16 may be readily telescoped into the neck 13 to the position of FIG. 3 with the securing means 38, 40 in a loose condition. The element 14 is then effectively positively secured to the flask neck by the simple tightening of the securing means as discussed above.

As best seen in FIGS. 1 and 5, the tubular body portion 16 may be provided with a plurality of annular outwardly opening grooves 41. One such groove 41a extends between the outer ends of the slots 27 and thus the presence ofthe slot portion 29 is effectively hidden to enhance the aesthetic charcteristics of the element 14. As shown in FIG. 1, the handle 17 may be provided with a surface configuration further enhancing the aesthetic characteristics of the element 14. As the element 14 may be formed by molding, such surface structures for improved aesthetic effect may be readily provided as desired. For further improved aesthetic effect, at least one of the tabs 30 may be provided with a recess for receiving the projecting portion of the securing means. Thus, as shown in FIG. 4, one of the tabs 30 may be provided with a recess 42 at least partially receiving the nut 40. As shown in FIG. 5, the recess 42 may have a cross-section similar to the outside configuration of the nut 40 so as to serve as means for holding the nut against rotation during threading of bolt 38 therein.

The unitary construction of the spout and handle element 14 provides improved maintenance facility. As the elements of the device are maintained integral, the device may be readily installed and removed relative to the flask neck and may be readily maintained as by normal cleaning methods. As the recess 25 opens axially, the O-ring 26 may be readily removed and installed as desired for further facilitated maintenance.

While the discontinuously lower body portion 23 permits facilitated installation of the element 14 on the flask neck, effectively positive retention thereon is obtained by the improved constriction and mechanical interlock means discussed above provided by the slotted structure and cooperative securing means.

Turning now to FIGS. 6 and 7, a modified form of liquid serving device, generally designated 110, is shown to comprise a device generally similar to device 10 but having a lower body portion 1 16 provided with a single slot 127 wherein the transverse portion 129 extends from a single tab portion 130 with the handle base portion 132 being provided with a single'recess 131 extending approximately one-half the width of the base portion 132, as shown in FIG. 7. Thus, the device 110 provides the desirable flexible constrictive mounting on the flask neck.

As illustrated in FIG. 7, the securing means may comprise a bolt 138 which is threaded into a threaded hole 140 in the base portion 132.

In FIGS. 8 and 9, another modified liquid serving device, generally designated 210, is shown to comprise a device generally similar to device 10 but wherein the slot 227 includes a pair of spaced transverse portions 229 and the lower body portion 223 includes a continuously annular bottom section 243 whereby the tab 230 may be received in a recess 23] spaced above the bottom 233 of the handle base 232 and, more specifically, intermediate the bottom 243 and top 244 thereof. As shown in FIG. 9, a pair of slots 227 may be provided extending from opposite sides of the web 234 and the bolt 238 may be threaded into the web to effect the desired securing of the device 210 to the flask neck. As will be obvious to those skilled in the art, the different forms of securing devices illustrated in the different embodiments may be utilized interchangeably therein within the scope of the invention.

In FIGS. 10 and 11, another form of liquid serving device, generally designated 310, is shown to comprise a device generally similar to device 10, but having a slot 327 which does not extend transaxially into the annular lower body portion 323. Rather, as shown, the slot extends upwardly from the bottom surface 333 of the handle base approximately one-half the height thereof and narrows from the lower body portion 323 into the handle 317. The securing means bolt 338 may be threaded into the far half of the base portion, as shown in FIG. 11, to effect the desired constriction and formation of the mechanical interlock of the device 310 relative to the decanter neck. 7

The. liquid serving devices of the invention may be provided with another form of sealing means in lieu of the O'-ring 26, as illustrated in FIG. 10, wherein the upper body portion 322 is provided with a plurality of radially inwardly opening grooves 325. The upper body portion 322 has an internal diameter slightly larger than the outer diameter of the flask neck 313 whereby a body of plastic 345 may be set therein to effectively seal the device 310 to the flask neck 313. Illustratively, the set plastic may comprise a set body of a suitable epoxy resin. The grooves 325 extend continuously annularly whereby the plastic 345 set in situ thereineffectively defines an improved annular seal of the device 310 to the flask neck Except as otherwise noted above, each of the devices 110, 210 and 310 is similar to the liquid serving device 10. Similar portions thereof are identified by similar reference numerals but LQO di f fren t.

Thus, the invention comprehends an improved liquid serving means whereina unitary spout and handle element is provided for facilitated installation on the neck of a decanter flask. The devices of the illustrated embodiments are extremely simple and economical of construction while providing the highly desirable features discussed above.
